ABSTRACT:
The recovery of water-free desorbates from adsorption filters hampered not only by desorption with water vapor but also by water which is adsorbed at the adsorption media from the gas or the air to be purified and which water is likewise driven out during the desorption. It has now been found that desorbate without water can be recovered if the gaseous desorption medium is pre-dried in a water sorption filter with an adsorption medium having water-selective action, before entering the condenser-cooler. Bypasses avoiding the sorption water reservoir as well as the condenser-cooler also permit operating conditions which go beyond the normal desorption, namely, desorption with increased temperature for driving out less volatile residual loads as well as reactivating desorption. In a particular embodiment, the sorption heat accumulator can be combined with the condenser-cooler, an embodiment which can be employed particularly for recovery equipments.
